Most polystyrene insulated door can be thicker but have a lower R-Value than polyurethane. If you're searching for thermal efficiency and also a high R-Value, don't be misled by the thickness of the door! A polyurethane Garage Door might seem thinner but really offers a much greater insulation R-value. That is due to how the insulation expands through the production process to tightly fill the cavity between both steel panels as it bonds to the skins of the doorway. Not only does this make the door better insulated, it also makes the door amazingly strong and helps minimize noise whilst the door works. How long your door will survive, what sort of punishment it might take, or even how much annual maintenance it'll need is strongly determined by the stuff used to make the doorway.
